There were two new batches of sam50 tasks for Windows but if you blinked, you missed them.

#877 and #878 have had all tasks waiting to go out withdrawn as many produce uploads greater than the limit allowed causing some to fail at 100% completion. They will be re-issued shortly.

Edit: Those already sent out will be left to run. Credit will be granted.


I have few of these, should I let them finish or should I abort?

I am letting mine run. but I have edited my client_state.xml as I described in a thread in the Linux section to increase the maximum file size. From that thread, also if you make sure the final zip finishes uploading before the task reports, that it seems also works. (with my bored band and if two are uploading at once they wouldn't stand a chance.)

Gott im Himmel! I acquired 33 Windows tasks! Oh well, that's half my cores busy for a bit. Is that the end of it or are more coming? My other 24 core xeon is upset it missed out.

More tasks wanting, dark side leave you must.

Nothing more for Windows has been flagged up as being imminent. However, that doesn't always mean anything. Sometimes it seems the availability of work is determined by a random number generator.

It was purely selfless, I felt sorry for the other computers.

It could be pseudo random. A maths Boinc project could be set up to work out the seed.

Message 62866 - Posted: 6 Nov 2020, 16:31:26 UTC

According to the server status page there are over 600 tasks available for UK Met Office HadAM4 at N216 resolution

From what I understand these are Linux tasks, but I am not getting any work when requesting it from my Linux system.

Are there any special requirements for these tasks that I am not aware of ?

Thanks,

Tom

There is a need for 32bit libraries as these are 32bit applications. See this post for commands to install the necessary libraries for common Linux distributions...

Can you post what you get in the event log when you request work from the project? - Many do succeed in getting work which they then crash due to not having the relevant 32 bit library files.

Also worth noting having requested work there is a back off period of one hour before you can request work again. If you do try earlier the hour's back off starts again.

And the message from Boinc doesn't help. I've had something along the lines of "Last request too recent: 6 minutes", which I assumed meant I was allowed to try again in 6 minutes, but it's actually giving me the meaningless information that I tried 6 minutes ago, which is nothing to do with how long I actually have to wait!

No it tells you how long since you last tried.

In the projects tab you should see how long you have left in the back off before you can try again. Most projects have this but I don't know of any others as long as CPDN. (That may be just because I have no experience of most projects.)

I use Boinctasks, but it shows that in the projects tab too. I just wondered what the point of the message I got from the server was.

I assume CPDN has a long backoff due to small amounts of available work. If they didn't, computers would be pestering the server endlessly, although Boinc does automatically increase the time when it's unsuccessful.

Milkyway is the other place I encounter it. They only have a 90 second backoff, but their GPU tasks take 30 seconds, and the server refuses [1] to send new work at the same time as receiving results. So if I'm just running Milkyway, when Boinc gets low on work and wants more, it sends my completed tasks back at the same time, and doesn't get any work. It then has to wait 90 seconds and does the same again, never getting any work until I've completed everything. Then there's some hidden 8 minute delay (Boinc client impatience?), which it ignores if I click update.

[1] I think due to a misconfiguration they refuse to (or don't know how to) fix. Someone complained to the previous project manager and got no response. I complained to the new project manager a few months ago and he said he'd look into it, but nothing ever happened.

I installed the 32-bit libraries for Ubuntu 18.04 LTS:

sudo apt-get install lib32ncurses5 lib32z1 lib32stdc++-6-dev

Everything installed fine, but I am still not receiving new work (same message as before):

Why can't Boinc servers hand out meaningful responses? There has to be a reason for no work sent, it should state it. Sometimes it does when it feels like it and says "project has no tasks available", or "you need more RAM for the available tasks" or something.

A new computer that I built earlier this year kept doing this.
I never did solve it.

Perhaps if he turned some debug logging on, there would be a meaningful response given to locate the problem? I've done that before with other projects. But don't turn everything on at once or it actually bogs down the whole machine writing logs!

I don't suppose the server has more detailed logs? If you have access to those.
